Abstract
The utility model discloses a parallax-free liquid crystal display riflescope optical system. The parallax-free liquid crystal display riflescope optical system comprises a visual system, an imaging system, a reticle system and an eyepiece group. The visual system comprises an object lens and a right angle roof prism which are arrayed at the side of an object. The imaging system is arranged under the right angle roof prism. The reticle system comprises a reticle and a display lens. The reticle and the display lens are disposed at the side of the object and are axially parallel to the object lens and the right angle roof prism. The eyepiece group is disposed at the side where the imaging system is arranged backwards to the object. The imaging system is imaging prism or a reflection system formed by a first reflector and a second reflector. The reticle is a liquid crystal screen. The parallax-free liquid crystal display riflescope optical system has following beneficial effects: the imaging system enables the reticle system and the visual system to be coaxially arranged and imaged on the same focal plane; theoretically, a parallax-free product is achieved; a backlight LED screen is used as the reticle so that the reticle has a rich variety of patterns and forms without presence of zero error during a process of changing the patterns; and therefore high pointing accuracy of a user is satisfied.
Description
Technical field
The utility model relates to optical instrument field, and especially a kind of no parallax liquid crystal display demonstration rifle is taken aim at optical system.
Background technology
It is all to adopt the form of graticle or division line to carry out run-home that current traditional rifle is taken aim at optical system, this optical system graticle pattern form can not change, if make the variable mechanical variable division plate of pattern, can only adopt other light path (utilizing spherical reflector catoptric imaging), caused like this graticle and visual optical system not coaxial, can produce the axle that cannot eliminate and aim at parallax outward, and mechanical height can exist very large zero-bit repeatability error, pointing accuracy cannot meet high-precision user's requirement.
Summary of the invention
For solving the problems of the technologies described above, the technical problems to be solved in the utility model is to provide one.
The technical solution adopted in the utility model is: a kind of no parallax liquid crystal display demonstration rifle is taken aim at optical system, comprising:
Visual system, comprises the object lens, the right angle roof prism that from object space one side, line up; The light that described right angle roof prism sees through object lens by level changes 90 ° of directions of propagation;
Close picture system, be arranged under right angle roof prism, described in close picture system and receive light the imaging of right angle roof prism vertical transfer;
Graticle system, comprises and is positioned at object space one side the graticle parallel with object lens, right angle roof prism axle and shows lens;
Eyepiece group, is positioned at and closes a picture system side of object space dorsad;
Described visual system and graticle system ECDC are upper and coaxial as same of being imaged on of system, described in to close as system be coincidence prism or the reflecting system that is comprised of the first speculum and the second speculum; Described graticle is liquid crystal display.
Described eyepiece group comprises successively field stop, additional mirror, balsaming lens, the eyepiece monolithic from closing picture system, to human eye visual angle, arranged, described in close the field stop that is imaged on as system and graticle system.
Described liquid crystal display is positioned at and shows outside 2 times of focal lengths of lens.
Described liquid crystal display is backlight LCD screen.
Described object lens are cemented objective.
The beneficial effects of the utility model:
Of the present utility model closing as system makes graticle system and visual system realize coaxial and be imaged on same focal plane, product can be accomplished no parallax in theory, adopt backlight LCD screen to do graticle, its graticle pattern form is changed more, and there is not the error of zero in change in pattern process, thereby can meet the higher pointing accuracy that user requires, LCD display mode backlight also can obtain more comfortable observation effect.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described further.
Fig. 1 is the first example structure figure that a kind of no parallax liquid crystal display demonstration of the utility model rifle is taken aim at optical system;
Fig. 2 is the second example structure figure that a kind of no parallax liquid crystal display demonstration of the utility model rifle is taken aim at optical system.
The specific embodiment
Shown in Fig. 1-Fig. 2, for showing rifle, a kind of no parallax liquid crystal display of the present utility model takes aim at optical system, comprising:
Visual system, comprises the object lens 1, the right angle roof prism 2 that from object space one side, line up, and is arranged on the picture system of closing under right angle roof prism 2; The light that right angle roof prism 2 sees through object lens 1 by level changes 90 ° of directions of propagation; Close light the imaging of picture system reception right angle roof prism 2 vertical transfer;
Graticle system, comprises and is positioned at object space one side the graticle 3 parallel with object lens 1, right angle roof prism 2 axles and shows lens 4, graticle 3 is positioned at and shows outside lens 4 two focus length;
Eyepiece group, is positioned at and closes a picture system side of object space dorsad, comprises field stop 5, additional mirror 6, balsaming lens 7, the eyepiece monolithic 8 from closing picture system, to human eye visual angle, arranged successively;
As shown in the figure, visual system and graticle system be imaged on 5 of field stops on the whole and visual system and graticle system coaxial.
Figure 1 shows that the first embodiment of the present utility model, closing as system is coincidence prism 9, and graticle 3 is liquid crystal display, on the one hand, irradiate the light of testee by object lens 1 and right angle roof prism 2, through the light path of coincidence prism 9, turn back and be imaged onto on focal plane (field stop 5 place faces); On the other hand, liquid crystal display shows by showing that lens 4 and coincidence prism 9 are imaged onto on focal plane.Meanwhile, the imaging of object space and the imaging of liquid crystal display overlap on same focal plane, then are imaged onto infinity through eyepiece group.
Figure 2 shows that the second embodiment of the present utility model, closing as system is the reflecting system being comprised of the first speculum 10 and the second speculum 11, and graticle 3 is liquid crystal display.Different from the first embodiment is, after object space scenery light incident object lens 1, after right angle roof prism 2 changes 90 ° of directions of propagation, it is the reflection of the first speculum 10 and the second speculum 11, make its imaging and focusing to field stop 5 positions of eyepiece, through eyepiece group, be imaged on infinity again, formed a telescope optical system with multiplying power.The light of liquid crystal display displaying contents is after showing lens 4, after the transmission of the first speculum 10, at field stop 5 places, form a real image dwindling, coincide together with object space scenery target light line imaging, to eliminate both parallaxes, through eyepiece group, be imaged onto infinity again, reach so the effect of simultaneously seeing scenery target and liquid crystal display content clearly.
In addition, liquid crystal display is backlight LCD screen, and LCD display mode backlight can allow user obtain more comfortable observation effect; Object lens 1 are cemented objective.
Of the present utility model closing as system makes graticle system and visual system realize coaxial and be imaged on same focal plane, product can be accomplished no parallax in theory, adopt backlight LCD screen to do graticle, its graticle pattern form is changed more, and do not have the error of zero in change in pattern process, thereby can meet the higher pointing accuracy that user requires.
